This invention relates to clamps, but more particularly to aclampadapted for securing a flexibleconduit to a nozzle or pipe connection.

j One object of the inv ention is toassure a durable and rugged clamp ofsimplified con-- struction and which maybe used in connection withconduits of different diameters.

Other objects will be in part obvious and in part pointed outhereinafter.

t Figure 2 is atransverse view taken through Figure 1 on theline 2-2looking in the direction indicated by the arrows, and

Figure 3 is a perspective view ofa detail. Referring more particularlyto the drawings, the clamp, which 7 is designated generallyby A, isshown applied to a conduit B for clamping the conduit to a coupling C. a

The clamp comprises a pair of members D and E herein shown as rods orbolts.

respects and accordinglyeaoh is provided with a curved portion F adaptedto conform tially from the portion FL At the free end of each curvedportion Fis a lateral ear H hav-' ingan aperture J thereinot somewhatlarger The members D 'andIE are disposed about the conduit B to form aloop and the arrangement is such that the straight portion G of one ofthe members extends through the aperture J in the ear H of thecomplementary member. The portions G are threaded as at K to receivenuts L for drawing the members D and Etogether and thereby exerting apressure on the conduit B. a

In the present instance means vare provided for distributing thepressure of the members D andE over a wide area of the conduit B.

7 To this end a pairlofplates O and Pare disposed about'the. conduit Bto'form seats for the members Dana 11 respectively. lhe

the other-plate. The plates may be uniformlytaperedtrom the end-portionR- to almife plates as' the nuts are being tightened to draw thememb'ersD andE'together. 7 On each oi'the plates are formed integral'fclips or hooks S whichproject from the outer surfacesof the plates'andare suitably curved over the members D and .E for holding the membersagainst movement longitudinally of The members D and E howtuallyseparated; a

1 f To the end that the clamp may be usedon conduits of smaller diameterthan those to which the clamp is intended to belnormally applied, themembers D and E may be formed of a suitable iiefriblematerial to permitbendmg of the members to conform to the contour v of such conduits; {Inthe assembling of'the clamp on'such conduits of smaller diameter,

one of the nuts Lfimay be threaded on a straight portion 1G 'tothe usualdepth and the other nut-L drawn up tightly-on its corresponding portionG, thus drawing anysurplus length of the loop entirely through one ofthe ears H. Assembled in this manner, the
